Thank Shiver. He found it.
I think it’s hard to cause a macro-injury to the penile tissues when conservatively performing PE. A macro injury would be a torn ligament or a burst tunica.
The goal of PE, as I understand it, is to use our bodys’ collagen-producing factories to our advantage by encouraging growth of the ligs and/or tunica in the desired direction.
I recently posted a thread about bone lengthening. It seems to me that PE is analogous to bone lengthening. First, you cause some trauma (cutting the bone, or, with PE, hanging to fatigue). The trauma causes an inflammatory reaction which creates a soft bridge. In bone lengthening, this is certainly a macro-injury. In PE, it’s micro-tears. Over time, by application of tension, the bridge is then “distracted,” or stretched. The continued inflammation kicks the fibroblasts into action to output collagen, and growth ensues in the direction of the applied stress. New, healthy tissue fills the void.
Obviously, one can go too far in causing damage. If inflammation becomes chronic, it can cause fibrosis and scarring. The line to walk, then, seems to be one at which healthy recovery coexists with continued, low grade inflammation. Bib called this state “fatigue.” You feel the stretch, there’s some dull aching, and you’re unable to maintain your maximum hanging weight over multiple sets. If days go by and you can’t get back to your max, you’re probably overdoing it. On the other hand, if you can hit your max whenever you want to, you’re probably not doing enough.
To summarize the above drivel, you always want to keep injury at least slightly ahead of healing.
